It is worthy to mention that god, according to the bible, wiped out entire cities that did not want to follow his rule. If god didn't want us to do it, we would not be able to: We'd be nuked.

On the other hand...

"The fear of the LORD is the beginning of knowledge, but fools despise wisdom and instruction." - Proverbs 1:7
"The beginning of wisdom is: Acquire wisdom; And with all your acquiring, get understanding." - Proverbs 4:7
"Day after day they pour forth speech; night after night they reveal knowledge." - Psalm 19:2
"The heart of the discerning acquires knowledge, for the ears of the wise seek it out." - Proverbs 18:15
"Gold there is, and rubies in abundance, but lips that speak knowledge are a rare jewel." - Proverbs 20:15

... Looks like it is God's will for us to know! (it figures, otherwise we'd have no brain... right?)
